Abstract: A process is claimed for the bending of glass sheets on a frame by gravity during which one or more stacked sheets, arranged on a bending frame are raised to the deformation temperature and allowed to take the shape of the bending frame by gravity. There are at least two bending stages using gravity involving being supported:- at the periphery along a primary peripheral line during the first stage; and along a secondary peripheral line during the second stage. The passage from the primary stage to the secondary stage is realised by controlling at all times the action of the forces exerted on the parts of the sheet or sheets of glass coming into contact with the secondary peripheral line, by reaction of this secondary peripheral line to this contact. The device used to put this process into service is also claimed and incorporates a pivot device to move for the primary bending stage to the secondary bending stage.

[Class 75 (iv).] A searchlight comprises a reflecting surface of revolution adapted to intercept rays from the front half of a source of light and to direct them towards a small region substantially coinciding with the focus of a projection lens, the rays being re-directed from this small region on to the lens by means of a small reflecting cone or like surface of revolution situated on the common axis of the searchlight. The reflecting surface 6 may be made in one or more parts and may be generated from an arc of an ellipse having one focus at the rear end of a filament 1-1a arranged along the common axis X-X and the other focus close to or at the focus 0 of the lens 9, or from an arc of a circle having the mean curvature of such an ellipse.

Abstract: 580,043. Range-finders. BARR & STROUD, Ltd., and FRENCH, SIR J. W. Jan. 22, 1944, No. 1252. [Class 97 (i)] In a coincidence or stereoscopic range-finder the objectives. are made of comparatively long focal length and the image beam is doubled upon itself one or more times in order to accommodate it within the instrument. As shown, a beam of light from the right-hand end is reflected by a pentagon 3, through an objective 5 of long focal length, through a prism combination 8 to a totally reflecting prism 16, finally being reflected by a face 17 of the prism 8 to form an image in an image plane 9 which is viewed by an eyepiece 10. Light from the left-hand end is transmitted through a similar system. The range is determined by the position of the eyepiece when the two images are coincident and in good focus, or, in a stereoscopic instrument, when the image appears in the plane of reference marks. Alternatively, a translating prism may be used. To correct for refractive errors in the observer's eye, a spectacle lens may be fitted to the eyepiece or, where the latter carries a range scale, provision is made for setting the scale to zero by focusing on a mark provided in the field.

Title: Improvements in the manufacture and treatment of fibres, yarns, fabrics, films and like materials having a basis of an organic ester of cellulose
IPC: D01F2/28
Filed: 1937-01-18
Abstract: Threads, fibres, yarns, fabrics, ribbons, films, and like materials made of organic esters of cellulose such as cellulose acetate, formate, propionate, butyrate, or mixed cellulose esters such as cellulose nitrate-acetate, acetate-propionate, acetate-propionate-nitrate, or cellulose ether esters such as ethyl cellulose acetate, oxyethyl cellulose acetate, are saponified by means of an aqueous bath containing in solution two salts of a weak polybasic acid, these salts containing different molecular proportions of the acid radicle.  The reaction of the bath is alkaline owing solely to the hydrolysis of one or both of these salts, the salt containing the lower proportion of acid radicle is present in an amount ranging from that theoretically required to produce the desired degree of saponification to twice that amount, and the salt containing the higher proportion of acid radicle is present in a proportion of 5-20 molecules to each 100 molecules of the salt containing the lower proportion of acid radicle.  Examples of the two salts are trisodium or tripotassium phosphate with disodium or dipotassium phosphate, the sulphides of sodium, potassium, calcium, or barium, with the corresponding hydrosulphides, and sodium or potassium carbonate with the corresponding bicarbonate. In the Provisional Specification the amounts and proportions of the two salts are not limited. Specification 469,025 is referred to.

Title: Copolyesters
IPC: C08G63/181
Filed: 1956-01-18
Abstract: A copolyester is made by condensing ethylene glycol with a mixture of 90-15 mol. per cent of terephthalic acid or ester-forming derivative thereof and 10-85 mol. per cent of orthophthalic acid or ester-forming derivative thereof to produce a mixture of glycol tere- and orthophthalates and thereafter polymerizing these glycol phthalates.  The copolyester may be used for the production of films (which may be orientated), moulded and extruded articles, fibres and coatings.  Some of them are soluble in chloroform, ethylene dichloride, trichloroethane, dioxane, tetrahydrofuran, nitroethane and a mixture of phenol and tetrachloroethane.  In an example, ester-interchange was effected between ethylene glycol, dimethyl ortho phthalate and dimethyl terephthalate by heating at 197 DEG  C. in presence of litharge.  The temperature was maintained at 197 DEG C. while the pressure was reduced to 0.1 mm. of Hg. and the excess glycol distilled off. Then the temperature was raised to 260 DEG  C. and the pressure increased to 1 mm. of Hg. and finally the temperature was raised to 280 DEG  C.

Title: Antisurge system adapted to prevent the stalling of turbine aero-engines

Filed: 1964-01-15
Abstract: 1,56,811. Fluid-pressure servomotor systems. SOC. NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION. Jan. 15, 1964 [Jan. 16, 1963], No.1764/64. Heading G3P. [Also in Division F1] Means for preventing surging and stalling of an aircraft turbojet engine comprises a pair of diaphragms 2, 58 rigidly interconnected by a member 62 and defining a chamber 3 connected by passages 11, 12 or by a restriction 59 with an engine pressure that fluctuates in the event of an incipient stall, e.g. the pressure at the compressor discharge or in the combustion chamber, a chamber 4 connected through a restriction 5 also with the pressure P2, and a chamber 60 open through a passage 61 to atmosphere. Normally, the pressures in the chambers 3, 4 are equal and the diaphragm assembly is positioned as shown, with a valve head 65 permitting communication through the passage 12. As surging commences the pressure P2 falls and, due to the restriction 5, the diaphragm assembly is moved to the right to operate a spring-loaded abutment 66 which unloads the combustion chamber through a transmission comprising an electric switch and relay etc., or a hydraulic or pneumatic leak. The unloading may be effected by opening a fuel by-pass valve, reaction jet nozzle, or compressor unloading valves, or by adjusting the angular setting of the engine stator blades. The rightward movement of the diaphragm assembly also closes the valve head 65 and opens a valve head 63 which allows atmospheric pressure to become effective, through passages 68, 69, 70, in the chamber 3 to cause the diaphragm assembly to remain in the rightward position until, after a time lag or in response to action by the pilot, fluid pressure is applied to a chamber 73 to close a valve 76 in the passage 70 so that P2 pressure is again effective in the chamber 3 through the restriction 59 to reset the diaphragm assembly to its normal position. Release of the pressure in the chamber 73 prepares the apparatus for subsequent operation.
